Raynaud's Disease
Raynaud’s disease is a condition caused by constriction and spasms of small arteries, primarily in the hands after exposure to cold. Frequently, white or bluish discoloration of the hands (and sometimes toes, cheeks, nose, or ears) will occur after exposure to cold or emotional stress. The cause of Raynaud’s disease is unknown. A condition called Raynaud’s phenomenon causes similar symptoms, but it is the result of connective tissue disease or exposure to certain chemicals. The same natural remedies are used to treat both disorders.
What are the symptoms of Raynaud’s disease?
Fingers (generally not the thumb) or other affected parts of the body may feel numb or cold during an episode, and later, after warming, may become bright red with a throbbing painful sensation.
How is it treated?
People with Raynaud’s disease are commonly advised to dress warmly during the winter and to avoid tobacco use and unnecessary exposure to cold, especially of the affected parts. Conventional treatment also includes medicines such as calcium channel blockers and sympatholytic agents. In severe cases, sympathectomy (surgical interruption of sympathetic nerve pathways) may be recommended.
Lifestyle changes that may be helpful:
Dressing warmly and wearing gloves or mittens often help prevent attacks of Raynaud’s disease. Individuals with Raynaud’s disease should not smoke, because nicotine decreases blood flow to the extremities. Women with Raynaud’s disease should not use birth control pills, as this method of contraception can adversely affect circulation.
